Why I cann`t run the following case? It says there are sth. wrong at
"onCreateOptionsMenu","onOptionsItemSelected"&"onPrepareOptionsMenu" .
package com.demo.menu;
import android.app.Activity;
import android.os.Bundle;
public class MenuDemo extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0,0,0,"1");
menu.add(0,1,0,"2");
menu.add(0,2,0,"3");
menu.add(0,3,0,"4");
menu.add(0,4,0,"5");
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
TextView view = (TextView) findViewById(R.id.text_view);
switch (item.getItemId()) {
case 0:
view.setText("This is"+item.getTitle());
break;
case 1:
view.setText("This is"+item.getTitle());
break;
default:
view.setText("Debug.");
break;
}
return false;
}
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
return super.onPrepareOptionsMenu(menu);
}
}
